BBC News - David Cameron to make more government data available
Mr Cameron said he wanted to rip off the "cloak of secrecy" around government and public services - and extend transparency as far as possible.
Data being made available includes items of major government spending and the pay of top civil servants.
Mr Cameron outlined plans for freeing up the information in a letter to all government departments.
He said: "Greater transparency is at the heart of our shared commitment to enable the public to hold politicians and public bodies to account."
Details of large government contracts will be published from September, items of central government spending from November and local government spending over £500 from next January.
I am surprised by the lack of response to this initiative. It seems that, as yet, big money has a very tight strangle hold on this whole industry segment.
